PID Duct Panel

It is a high-performance ventilation duct product, which is widely used in HVAC systems. The following is a detailed introduction:

Basic Structure: It is a sandwich structured panel. The core is polyisocyanurate (PIR) foam, which is a closed-cell insulating material. The two outer layers are aluminum sheets or aluminum foils.

Panel Structure: Silver Alu. Foil/ PIR Foam/ Silver Alu. Foil
Foam Density: 50-55kg/CBM
Panel Dimension: 3950mm*1200mm*20mm or 2900*1200*20mm
Alu. Foil: 60 or 80 Micron (Embossed)
Fire Rating: Class 0 (BS476Part 6&7) or Class A (ASTM E84)

Main performance of PID Duct Panel

1. Excellent thermal insulation performance

Polyurethane material itself has an extremely low thermal conductivity, typically ranging from 0.018 to 0.022W/(m · K), which can effectively reduce heat loss or cold leakage during the operation of air conditioning systems. Compared with traditional glass wool air ducts (with a thermal conductivity of approximately 0.047W/m · K), under the same insulation requirements, polyurethane composite air ducts can significantly reduce energy consumption, achieve better energy-saving effects, avoid problems such as decorative damage and mold growth caused by condensation, and ensure a comfortable and healthy indoor environment.

2. it is lightweight, high-strength and easy to install

The PID Duct Panel is lightweight, approximately one-third of the average weight of traditional iron sheet air ducts. This feature not only reduces the overall load of the building but also lowers the requirements for the building structure accordingly, making it particularly suitable for high-rise buildings or large-span Spaces that are sensitive to loads.

Meanwhile, the lightweight panels make the handling and installation during the construction process much easier, significantly reducing the labor intensity of the construction workers. The installation process is relatively simple. It is bonded with polyurethane foam adhesive of the same origin as the core of the board, and combined with a special thermal break flange. All gaps can be fully filled with polyurethane foam, effectively preventing air leakage and cold bridge phenomena. The installation efficiency is significantly improved compared with traditional iron sheet air ducts, and the construction period can be shortened to about 1/5.

3. Excellent sound insulation and noise reduction function

This board adopts the micro-perforated plate noise reduction theory technology. Some products also use laser micro-perforation technology, which can effectively reduce the noise generated during the operation of the ventilation system. The vibration and echo generated during the operation of the air duct will be absorbed by the embossed aluminum foil and polyurethane foam. This gives the polyurethane composite air duct a distinct advantage in places with high noise control requirements, such as hospitals, schools, and office buildings, creating a quiet and comfortable indoor environment.

4. Environmentally friendly and healthy, durable

Polyurethane boards do not contain harmful substances such as Freon and formaldehyde. The production process is environmentally friendly and in line with the concept of modern green buildings. Compared with materials such as glass wool that contain carcinogens and can easily cause itching and redness when in contact with the skin, it is safer and healthier.

Furthermore, through the anti-corrosion and acid and alkali resistance treatment of the panels, the PID Duct Panel has excellent durability. Under normal usage conditions, its service life can reach more than 20 years, greatly reducing the cost and trouble of later maintenance and replacement.

5. Aesthetically pleasing and diverse, meeting personalized demands

The outer surface of polyurethane composite air ducts is usually made of color steel plates or aluminum foil with antibacterial coatings, featuring rich colors, smooth and flat surfaces, and excellent decorative properties. Whether exposed or concealed, it can blend in with the interior decoration style and add aesthetic appeal to the building. Meanwhile, different color options can also meet personalized design requirements, bidding farewell to the monotonous appearance of traditional air ducts.
